Priority Catchment

J12L

Barrydale (Doring Catchment)

Project Priority Area – J12L

1. Addresses ELU (QP water use) and not current use or unlawful water uses. 2. The project identifies users with or without registered use entitlements, whether claims for registered uses are correct, under-estimated, over-estimated or false 3. 2737 WARMS registered users in 3 Primary, 14 Tertiary and 68 Quaternary Catchments. 4. Expect another 30% unregistered users. 5. Quaternary J12L is a priority catchment – Ministerial instruction arising from court actions between users. Complete determinations end-March 2018. Currently in the verification phase. 6. V&V projects are multi-disciplinary / multi-faceted and have very high project management and coordination requirements – internally and externally. 7. User engagement (minimises ELU determination disputes) and BGCMA involvement (post-project continuity) are critical success factors.

8. Where an ELU has not been confirmed, the use becomes unlawful (s35(5)).

Summary: Project Specifications & Features

1. Project Team expectation – everything goes as planned. There are many project variables (internal and external) so planning is for a robust design that incorporates flexibility in approach. 2. User expectation – ELU engagements take place and determinations are available immediately or shortly after project commencement. 3. Generally – the elapsed time period creates several issues (e.g. property ownership and water user changes; uncertainty over extent of WU in the QP; missing / outdated information). Approach to mitigate: engage with users & property owners; work on confidence limits regarding determinations.

4. ELU determinations are NOT absolute and are approximations guided by evidence (visual or documentary) and legal principles.

Methodology – Summary

• The process includes identifying land and non-land based water uses (industrial, mining

and bulk potable water supplies, irrigation, crop types and impoundments) using remote sensing (RS)

techniques for the qualifying period.

• Crop irrigation requirements are estimated using the South African Procedure for

estimating irrigation WATer requirements (SAPWAT), version 4.

• The Gush Curves are used to quantify Stream Flow Reduction Activities (SFRAs) -

commercially afforested areas, converting areas to volume.

• The boundaries of farm reservoirs are delineated from RS and the volumes calculated

using a regression approach.

• Estimates of the irrigation water requirements, SFRAs and reservoir volumes form the

basis for interaction between the project team and water users to confirm their uses; and subsequently, to update the Water Authorisation and Registration Management System (WARMS), a database of water users.

(1) Provide tangible evidence of your QP water uses (documents, photographs, etc) (2) Note and adhere to the deadlines stipulated in your s35(1) letters when you receive these. (3) WUsers risk losing their WU entitlements should they not have their WUses verified. Continuation of the unverified use would then be unlawful. (4) WUsers are requested and advised to please contact the project team using the project email address if they have not provided the project team with their contact details or have not been contacted by the project team.
